Hand tendonitis

Tendinitis of the hand is a reaction of a hand tendon to overuse. The tendon becomes irritated. As a result of this irritation, the tendon swells and becomes painful. Moving and using the hand therefore becomes more difficult.

What causes tendinitis of the hand?

Tendinitis of the hand is usually the result of overuse of the hand muscles. Emerging technology around smartphones and other technological developments form an increasing risk of hand injuries.

Examples of tendinitis in the hand are a trigger finger and a mallet finger. A trigger finger is originally an inflammation of the tendon sheath, the tunnel through which the flexor tendon runs from the hand into the finger. The tendon thickens and its passage through the sheath is impeded. In a mallet finger, the extensor tendon at the fingertip is torn. This causes an inflammatory reaction.

There are many different tendons in the hand that can become inflamed. The tendons that extend and flex the fingers are often involved.

What are the symptoms of tendinitis of the hand?

With tendinitis of the hand, pain is one of the most common symptoms. This may be accompanied by swelling and/or local redness and warmth. Even if this is not clearly visible or palpable, it may still be present.

In the case of a trigger finger or mallet finger, straightening the finger also causes problems. Extension will be jerky or, at times, the finger may even remain in a flexed position and it is not possible to straighten it independently.

How is the diagnosis of tendinitis of the hand made?

Tendinitis of the hand is only rarely difficult to recognize. Usually the symptoms are superficial and can be well diagnosed by the family doctor or physical therapist. A physical examination, possibly supplemented with specific hand and/or finger tests, will provide a clear picture of the symptoms.

If there is doubt, the family doctor can refer you for further tests at the hospital. An ultrasound will in all likelihood provide sufficient additional information for the diagnosis of tendinitis of the hand.

How is tendinitis of the hand treated?

The first treatment goal for tendinitis of the hand is to reduce inflammatory symptoms such as pain, swelling, warmth, and stiffness. Getting sufficient rest and moving within the pain limits are of great value.

A physical therapist is ideally suited to guide you through this recovery process. They can also add value with possible treatment methods such as massage, taping, or frictions of the tendon. For a trigger finger, fitting a (night) splint can give the tendon more rest.

If the result is insufficient, there is also the possibility of further treatment by a specialist at the hospital. Think of an injection with anti-inflammatories or surgery.
